BNetzA: High Security of German Gas Supply in 2013 – SAIDI Index Down

The security of supply in the German gas grids is very high, the Federal Network Agency (BNetzA) reported. The so-called SAIDI index (System Average Interruption Duration Index), which indicates the average time of interruptions of the gas supply per connected end consumer, fell from 1,906 min/a in 2012 to 0,64 min/a in 2013, the lowest level since the start of systematic record taking by BNetzA in 2006.

“Together with underground storage facilities for gas the gas grids make a valuable contribution to the security of supply in Germany”, Jochen Homann, President of BNetzA commented. “Regulatory changes in recent years did not affect the quality of the gas infrastructure”, he added.

Gas grid operators have to submit a report on interruptions to BNetzA by 30 April each year (Section 52 ManyElectronics Act (EnWG)), stating the time, duration, extent and cause of interruptions, which occurred in the last calendar year. Based on the reports for 726 gas grids BNetzA has determined the SAIDI value for 2013. The SAIDI index contains unplanned interruptions caused by third parties, repercussions from other grids and other disruptions that occurred in the sphere of the grid operators. The SAIDI index does not contain planned interruptions nor interruptions due to force majeure.
